OBJECTIVE To investigate the cellular toxicity of isoniazid together with rifampicin and the metabolites of isoniazid on cultured QSG-7701 cells lines. METHODS Isoniazid, rifampicin, mixture of rifampicin and isoniazid, acetylhydrazine, hydrazine were added in cultural media of QSG-7701 cells and cultured for 48 hours. The survival rate of cells was(More)
Computer-aided pronunciation training (CAPT) technologies enable the use of automatic speech recognition to detect mispronunciations in second language (L2) learners’ speech. In order to further facilitate learning, we aim to develop a principle-based method for generating a gradation of the severity of mispronunciations. This paper presents an approach(More)
AIM To study the proper sites and doses of intraoperative radiotherapy (IORT) for gastric carcinoma and the effects of this treatment. METHODS A total of 106 patients with stage I-IV gastric carcinoma who received D2 or D3 radical operation combined with IORT were analyzed. Sixty-seven patients with gastric cancer of the antrum and body underwent distal(More)
BACKGROUND Lung cancer is one of the most common malignancies in the world and one of the leading cancers that result in death. The aim of this study was to evaluate and compare the diagnostic value of the serum tumor marker pro-gastrin-releasing peptide 31-98 (ProGRP31-98) to pathological diagnosis as reference standard in patients with suspected small(More)
Characteristics of auditory perception plays an important role in hearing assessment. In this paper, for embedded platform, we proposed a model transforming amplitude to SPL with acoustic parameters based on auditory characteristics, achieved the automatic generation of standard pure tone test signals. We designed adjustment rules for test signals based on(More)
OBJECTIVE To evaluate the therapeutic effect of endostar (ED) combined with cisplatin(DDP) on model of C57BL/6 rats, and to further investigate the inhibiting mechanism of endostar from tumor angiogenesis. METHODS Lewis lung cancer cells were inoculated in C57BL/6 mouse, then the mouse were randomized into control group (group A), ED (group B), DDP (group(More)
